KTB Rider Profile

Rides around 520 times a season, almost all on the flat, winning on 16% of them — level with the margin-free market read across five seasons (Fair A/E 1.01). Riding last-time-out winners the record reads 21% (439 rides). The rider is quiet just now — 2 winners in the last fortnight, below their own baseline.

The read

It is weakest at Ascot (8.9% over 45 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 21% (n=439, Fair A/E 1.07), but rides in big fields of 14 or more have been a poor signal at 11.1% (n=867, Fair A/E 0.99). Right now the rider is in a quiet spell: 2 from 19 rides in the last 14 days (10.5%, 5.1pts below the 15.6% baseline). F-H Graffard supplies 10% of the rides and beats the rider's average (23.5% vs 15.6%, A/E 1.00) — the market has that partnership priced right. The record reads poorly on Good to Firm going — 8% over 50 rides, 7.6pts below the baseline. 595 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Qatar Prix de l'Arc de Triomphe at Longchamp (FR) (Oct 2008, £1,680,588). The standout partner of the record: Vazirabad (FR) — 11 wins from 15 rides together. Seasonally, the rider fires Nov–Feb.

Each tile is the record in that situation vs the 15.6% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

Runs, wins and places only: a strike rate or a return on a handful of runs is noise, so none is quoted per horse — each horse's full record is on its own page.

In our archive from its very first year (2005), so this career almost certainly began earlier than our record does. The figures above count 2005 onwards only — what the archive holds, not a full-career total. This card is the full archive census (2005→); the statistics in the header aggregate from 2008 — the floor that guarantees every horse a complete captured career — so this card can legitimately show more wins than the header.

Top line: the rider's own record with each sire's runners (win %, wins–runs), same window as the header; faded under 30 runs. Beneath it: every run by that sire's progeny in our archive since 2008, as at 12 Nov 2026 — what they have done, not a forecast. A going or a distance is named only where at least 100 progeny runs sit 3 or more points from the sire's own win rate. Distance bands cover Flat and jumps together.

KTB’s figures on this rider’s mounts since 17 Oct 2026: fastest on KTB Speed in 1 run (won 0) · to 17 Oct 2026.

Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.

Quick answers

What is C. Soumillon's strike rate?
C. Soumillon has won 406 of 2,606 rides since 2022, a strike rate of 15.6% (as at 12 November 2026). Figures are computed from our own results archive.
Which course does C. Soumillon do best at?
Chantilly by strike rate: 135 wins from 738 rides (18.3%) since 2022. Read from the 15 courses with the most rides on the same basis, and only those with at least 30 — a small sample cannot top the list, and a rarely-visited course is not in the comparison.
Which yard does C. Soumillon ride most for?
F-H Graffard, with 268 rides since 2022 — 10% of the total. That pairing has won 63 (23.5%).
Is C. Soumillon in form?
In the last 14 days: 19 rides, 2 winners, a strike rate of 10.5%. That is below the baseline of 15.6% since 2022.
What is C. Soumillon's Fair A/E?
1.01, from 2,606 rides with a computed fair probability since 2022. Fair A/E compares actual wins with a margin-stripped market expectation, so 1.00 is par: above it the wins came at bigger prices than the margin-free market implied, below it they did not.
Fair A/E compares wins with a margin-stripped market expectation. Favourite-heavy samples — top yards, leading riders — naturally read a few points warm, so 1.05 means "beat the margin-free market read", not "the market underrates this by 5%". Three sample sizes are reported and never blended: runs (n), the ROI basis (n at SP), and the fair-A/E basis (n with a computed fair probability).

Strike rate is wins over all runs (n). ROI is £1 level stakes at SP over runs with a parseable price (n at SP). Fair A/E is wins over margin-stripped market expectation, over runs with a computed fair probability (n fair). The three Ns can legitimately differ and are always shown. Figures as at 12 November 2026, computed from our own results archive (2005 onwards; aggregates from 2008).
